Abstract

An embodiment of the invention discloses a method and apparatus for acquiring measurement value of functional magnetic resonance. The method includes: based on an average BOLD (blood oxygen level-dependent) time series, in a preset point-of-time range, of each voxel in an area to be detected as well as corresponding BOLD time series, in various time sequences, of all voxels, determining a selected time difference of each voxel, and determining a time delay figure of the area to be detected, wherein the time delay figure includes the selected time differences of all voxels and the time sequences are determined by multiple preset time differences in the preset point-of-time range and a preset difference-of-time range; and based on the time delay figure, determining a functional magnetic resonance measurement value. The embodiment has the advantages that analytical precision is improved, cost is lowered and safety is improved.

Description

technical field [0001] The invention relates to the technical field of magnetic resonance imaging, in particular to a method and a device for acquiring functional magnetic resonance detection values. Background technique [0002] Magnetic resonance imaging (MRI), also known as functional magnetic resonance imaging (Functional MRI, fMRI), is a very effective non-interventional technique for studying brain function and has become a widely used method for brain function research. [0003] fMRI can accurately and reliably localize specific cortical regions of brain activity with high spatial resolution and can repeatedly scan regions of interest in the brain in various ways. Hemoglobin includes oxygenated hemoglobin and deoxygenated hemoglobin, and these two types of hemoglobin have completely different effects on magnetic fields. Oxyhemoglobin is a diamagnetic substance and has no effect on proton relaxation. Deoxyhemoglobin is a paramagnetic substance, and its iron ion has 4...
